Sometimes my engine have problem with the low idle. It goes up to 2k, sometimes to 3k. Last night, I was draging it, shifting at 6500 on 1st, then ~5000 on 2nd, that was about it, then when i come to a stop, the idle is high, and sometimes continoue to go up. Any clues ?? Thanks guys

 

If you have cruise control it might be causing the problem...or you have a vacume leak somewhere. Adjust your idle screw and lower it and see if that works.

 

Are you doing this when the car is still cold or up to operating temperature?
